This is a bit off topic, but since there are plenty of letter-writers here I figured it'd be a good place to ask. I need to send a letter to Vancouver, BC from Tacoma, WA. Not very distant at all. The USPS website doesn't give any details about delivery times for first class, but I wondered if anybody had a general idea as to the time it will take to arrive. I want to time the letter to arrive in a 3-day period, if possible. Thanks.
